All Geronimo wanted was to live out his quiet gnome life drawing unicorns while imagining himself on epic adventures. It's not until his twelfth birthday that his parents offer him a real adventure. The gnome exchange program sends Geronimo to the north pole where he's sent on a perilous journey to save Christmas from Santa's evil half-brother. Encountering polar bears, centaurs, wizards, and demons along the way, the fate of the holiday rests in his tiny hands.
